An indirect evaporating cooling / condensing device comprises a blower, a shell body, a spraying
machine, a dividing wall type
heat exchanger, a wind inlet, a water pump and a water collecting plate, and an air-water
heat exchanger which is arranged on the wind inlet. The water pump pumps water from the water collecting plate and sends to the
water channel of the air-water heart exchanger, cools the environmental air inducted from the wind inlet enters the spraying
machine after being cooled; the water which flows out from the spraying
machine is sprayed on the outer surface of the dividing wall type
heat exchanger, the water flows back to the water collecting plate depending on the gravity; and the cooled medium which enters into the dividing wall type heat exchanger from the entrance is cooled by the water sprayed from the spraying machine and then flow out from the cooled medium exit. The invention not only can be used as the enclosed type
cooling tower, but also can be used as the evaporating type condenser; and compared with the prior art, the utility model can make the temperature of the out flowing liquid of the liquid with single-phase much lower in winter, and also can reduce the condensing temperature of the refrigerating and the chemical
liquid system; the utility model has cooling / condensing function for the whole year and is useful for the energy saving running of air-conditions, refrigerating and chemical systems.
